Direct coupling between servo motor and worm gear is one of the key strengths of EP worm gearmotors, which combine DC engine technology with exceptional strength and wear resistance. Motor and gearbox were created as you single, compact unit. Because of their reduced current draw, these gearmotors deliver more accurate control of working temperature and higher effectiveness.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based on this we are able to select a wide selection of regular customizations to meet the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special real estate such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with more than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out on your side.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox right into a single device (the first gear is directly on the electric motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our professionals will be happy to help you create your selection. We will be happy to send you documentation or design a suitable set directly, on demand.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being basic and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, easily running and highly powerful drive systems.
Our high-performance gear systems are built to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse installation positions and applications, making them much popular in the industry. Consequently our geared motors are often to be found as part of our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be utilized for the same torque, and smaller sized gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling contact to be substantially reduced and then the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
